Abstract:The field experiment were conducted at Research Cum Instructional Farm at IGKV, Raipur (C.G.) during kharif season of 2020-21, to know the seasonal incidence of green semilooper,
Chrysodeixis acuta on soybean. The incidence of Green Semilooper,

th SMW
i.e. third week of August with 0.7 larvae/mrl then it gradually increased and the maximum number of semilooper was observed during 39
th SMW

The correlation between Green Semilooper, Chrysodeixis acuta and weather parameters during kharif 2020 results indicated that the The Green Semilooper, Chrysodeixis acuta showed significant and positive correlation with maximum temperature (r= 0.595), minimum temperature (r= 0.561) and morning relative humadity (r= 0.610).
